927 N.W.2d 191
Iowa2019Background
- Invenergy/PAWE proposed a 340‑megawatt, up to 170‑turbine project in Palo Alto County; MidAmerican planned to acquire and operate it later.
- County Attorney drafted a new Wind Energy Conversion Systems Ordinance in 2016 after input from the Planning & Zoning Commission; Invenergy/MidAmerican provided suggested changes and warned that the project would not proceed without many of them.
- The Board adopted a modified ordinance (1500‑foot residential and cemetery setbacks; 30‑hour shadow‑flicker mitigation trigger) after three public readings; some developer suggestions were accepted and some rejected.
- PAWE submitted the site‑plan application; the Board held public hearings, received DNR and state archaeologist recommendations and an acoustician reanalysis, and granted conditional approval by a 3–2 vote.
- Landowners sued seeking declaratory and injunctive relief and certiorari review; the district court granted summary judgment for defendants and the Iowa Supreme Court affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Validity of ordinance (developer input) | Ordinance is unlawful because Invenergy/MidAmerican effectively wrote it | Ordinance was drafted by County Attorney; developer lobbying is lawful; Board exercised independent judgment | Court upheld ordinance; mere incorporation of private suggestions is not unlawful when Board makes its own decisions |
| Applicant/Owner‑Developer status | PAWE/Invenergy were not the true Owner/Developer because MidAmerican intended to operate; therefore application noncompliant | Ordinance permits transfer with Board consent; application disclosed anticipated transfer and MidAmerican participated in hearings | Court held substantial compliance and that transferability/consent provision allowed approval |
| Ignoring DNR/state archaeologist recommendations | Board acted arbitrarily by not following DNR one‑mile buffer and archaeologist survey recommendations | Board reviewed recommendations, found them too stringent, consulted local conservation director, and exercised discretion | Court found no arbitrary or capricious action; Board’s decision had adequate evidentiary support |
| Noise predictions and decommissioning costs | Acoustician reanalysis shows potential exceedance of 50 dB; decommissioning estimate ($33,480/turbine) likely underfunded | PAWE/Invenergy used conservative noise modeling assumptions and ordinance imposes limit/enforcement; decommissioning estimate prepared by licensed engineer and bond plus annual updates required | Court held Board reasonably relied on applicant’s noise study and engineer’s decommissioning estimate; conditions and enforcement mechanisms adequate |
